  The Consumer Data Right is a regulatory contract, not a commercial API product, so there is no
  vendor SDK team. The first-party libraries below are published by the Treasury Data Standards Body
  (npm scope @cds-au, maintainer npm-dsb) and by the ACCC's participant tooling programme (NuGet,
  GitHub org ConsumerDataRight). Probes of PyPI (consumer-data-right, cdr-au, consumerdatastandards),
  Maven Central, RubyGems, Packagist, crates.io and pkg.go.dev found no first-party client library.
